SCOOTER SKI Filed June 5, 1940 f Ha-1%; CZ/orey Patented Sept. 16, 1941UNITED STATES PATENT OFFICE 2,256,203 scoo'rR snr Ralph R. Hylan,Lexington, Mass. Application June 5, 1940, Serial No. 338,979 "1 claim.(cl. 2st- 23) My present invention relates to scooters and moreparticularly to ski scooters for use on snow and ice, the ski runnersbeing specially designed, the forward runner being pivoted.

The principal object of my invention comprises an improved scooter ski;

Another object is an improved scooter ski runner for use on snow; y

Still another object is an improved scooterl ski runner skate memberwhich is horizontally adjustable on the ski runner;

And still another object is an improved scooter ski runner skate memberwhich is removable, and

Other objects and novel features comprising the construction andoperation of my invention will be apparent as the description of thesame progresses.

In the drawing illustrating the preferred embodiment of my invention:

Fig. 1 is a side elevation of the scooter ski with the ice skate membersattached, the dot-anddash lines indicating adjustable positions of theice skate member on the rear ski runner member;

Fig. 2 is a top plan cross-section of the device taken on the line 2--2of Fig. 1;

Fig. 3 is a bottom plan view of the scooter ski, the ice skate membersbeing removed;

Fig. 4 is a cross-section taken on the line l-l of Fig. 1, portionsbeing shown in elevation and other portions being broken outforconvenience;

Fig. 5 is an enlarged cross-section taken on the line 5-5 of Fig. 1;

Fig. 6 is a top plan view of the rear ice skate member;

Fig. '7 is a side elevation of the rear ice skate member removed fromthe ski runner;

Fig. 8 is an enlarged perspective view of the hinge block member whichis mounted in the steering post, and

Fig. 9 is a side elevation of the ice skate member used on the front skirunner.

Referring more in detail to the drawing, I0 indicates the rear skirunner, and II indicates the front' ski runner. Preferably both thefront and rear ski runners are constructed from wood or other lightweight material.

On the upper surface of the front runner II I have provided a hingeplate member I2 having vertically extended hinge members I3. A steeringpost member, generally indicated at I4, and more specifically composedof two flat members I5, is provided. The lower portion of the steeringpost member is expanded to form a fork the lower ends of which arepivoted in the hinge portions I3 of the hinge plate member I2 by meansCil of the pin I6, the two ends of the fork being separated by thesleeve spacer member I'I which surrounds the central portion of the pinI3.

In the upper portion of the steering post fork is located the hingeblock I8, better shown in Fig. 8. The hinge block I3 is securely mountedbetween the inside surfaces of the fork by means of rivets or bolts I9which pass through the holes 20 in the block. The rear side of the hingeblock I3 is extended beyond the is provided with a substantiallyvertical bore 40. The top of the steering post I4 is provided with thesteering handle 2l which is affixed to right angle portions of thesteering post members I5 by means of the bolts 22. The upper portion ofthe members I5 may be solidly fixed together, as by rivets 23 or by anyother suitable means such as welding.

On the forward end of the ski runner III is mounted by means of therivets 24 a hinge plate member 25. The front end of the hinge platemember 25 is split at 26 to form two hinge portions 21 and 23. Thesehinge portions 21 and 28 are twisted toward each other and the outerends of each are curved to form loops 21a and 28a which fit over the topand bottom faces of the hinge block I8 adjacent the bore III. A hingepin 29 passes through the loops 21a and 23a and the bore 2| in the hingeblock I8 and completes the hinge assembly between the steering post Iland the rear ski runner hinge plate 25.

It will thus be seen that when the steering po Il is turned the frontski runner I I will pivot on the hinge pin 29 and at the same time thefront runner will pivot on its hinge connecting the lower ends of thefork of the steering post. When the front runner is turned, as abovedescribed both the front and rear runners will tilt at an angle.

When the scooter ski is used on the snow the bottom of the runners I0and II are as shown in Fig. 3 in which the central portion 30 and 3l ofthe runners leaving the high side edges 30a and 3Ia. These recessedareas 30 and 3| perform two separate functions. When the scooter is usedon the snow the high portions 30a and 3Ia prevent the runners I0 and Ilfrom skidding sideways, andwhen the scooter is used on ice they form apart of the slide ways for the ice skates 32 and 33.

It will be observed that the runner I0 is provided with a plurality ofholes 34 and the rear ice skate member 32 is provided with a like seriesof holes 4I passing through the top flanges of the member 32. Thevertical portion 35 of the ice member contacts with the ice andbesteering post fork andA III and II respectfully are recessed of therunners I0 and Il ice, and the adjustable feature makes it possiblecause of the tact that themember 32 may be adjusted toward the front orrear of the runner l it is possible to position the ice skate member inthe proper position to suit diiIerent conditions of use by differentsized people. Some people whol are short and have a shorter reach wouldstand nearer the forward portion of the runner I0 thereby depressing therunner too much in front of the skate member 32 but by moving the member32 forward such condition is corrected.A It will be seen from Fig. thatthe top of the` ice skate member I2 is flat and has approximately thesame thickness as the depth of the slide ways 30 and 3|.

'I'he front ice skate member 33 has a top portion which is curved to ntthe recessed portion 3| which blends into the curved under side of therunner toward its top. This front ice member 33 is removable Abut notadjustable being mounted to the runner Il through the holes 3'5, in thesame manneras in the case of the rear runner I0 and ice skate member 32.

When used as an ice scooter the bottom surface are raised above the toadjust the rear ice lmember 32 forward or back, as the case may be, sothat the center of gravity `pivoted to said rear Y of the user is in theproper place thus preventing the more iiexible forward portion of therunner il! from bending down and engaging the Vice.

When the ice members 32 and 33 areremoved the slide ways on the bottomof the runners i0 and Il provide guiding means to prevent the skirunners from slipping sideways or skidding on curves or slopes.

It .is to be understood that I may vary thi! shape and proportions ofthe various parts to suit various conditions in manufacture, etc.,within wide limits without departing from the spirit of the invention.

Having thus described my invention, what I claim as new is:

An improved scooter ski comprising in combination a front and rearrunner, a steering post runner, a rectangular slideway recess extending`all of the way along the lower surface of said rear runner, a T-shapedskate member located in said recess having the flat top face of the Tshape located in said recess slideway, said skate member beinglongitudinally adjustable in said slide way recess.
